REVERSING-SWTCHl Specification of Letters Patent.

Patented July 14, 1914.

Application filed November 1, 1912. Serial No. 729,111.

' To all whom it may concern:

Be it known that I, WILLIS S. MORSE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements 'in Reversing- Switches, of which the following is a spech tlcation;4 l

One object of my invention is to provide a novel form ofmeversing switch having its parts so arranged that its movable member may be adjusted relatively to an operating member connected to it; the invention contemplating a construction for accomplishing the above results, which is simple, compact,

substantial and not likely to get out of order.

I Vfurther desire to provide a forni of reversing switch havingan oscillatory actuating member adjustably connected `to its movable Contact in order to permit of the distance of said contact from either of two fixed contactsfbeing varied independently of said actuating member.

These objects and other advantageous ends, I secure as hereinafter set forth, reference being had to the accompanying drawin s in which:

j ignre 1 is a plan partly in section of a reversing switch constructed according to my invention, the cover of the casing being removed; Fig. `2 is a vertical section on the line olf-a., Fig.'1, Figa 3 is `a fragmentary elevation of a detail otmy'inventlon, and

Fig. 4 is a pla'fn of a modification of the invention.

In the above drawings, 1 represents an 1nclosing'casing in the-formrof a box to one side of .which is fixed abearing` 2 for an I oscillatory spindle 3, constituting` the actuating member of the switch. 'Ihe spindle 3 may be rocked in'its bearings 2 by any suitable means `(not shown) asior example by fis a member connected thereto whichl moves .or oscillates in response to changesinthe tension of a papir webv passing. through a printingpress or the like. The use of the switch is, however, not confined to printing presses as it isevident that the arrangement is susceptible of more general application.

The switch proper consists orn a support.- ing structure 4 in. the form of plate of insu-l lating material mounted within the casing l andhaving fixed to it three brush holders 5, 6 and 7 of rectangular section and respectively provided with binding posts or terminals 8, 9 and 10. These brush holders are mounted on the plate 4 so as to be substantially parallel and have certain or" their faces in substantially the same plane; there being a recess `or cavity in each of said faces' in which is mounted a spring pressed contact or brush 11 preferably made of carbon. Immediately adjacent these contact brushes I slidably mount a block 12 of insulating material such as fiber which is`held at a predetermined distance 'from the ends of the brush holders 5, 6 and 7 by a pair of guides 13 and 14, so formed as to allow it to move longitudinally, while preventing it from moving away from the surface of the plate 4. In ay suitable -recess in that face of the block'lQ engaged by the brushes 1l, I mount a metallic plate 15 whose outer face is preferably flush with the adjacent surface of said block and whose length is slightly less than the distance between the two onter-most contact brushes 11, so that when the block l2 is in its mid position its contact plate 15 while electrically engaging the central con- 'tact or brush 11- is disengaged from both of the outer contacts ll although relatively near the-same, In order to prevent injury to the plate 15 from arcing, I .mount in it adjacent its ends, two supplementary contacts in the form of carbon pieces 16 and 17."

In order to connect the movable switch member formed by the contact plate 15 and the block 12, with the oscillatory spindle 13, I mount on the upper end oit this lat ter an arm 18 and pivot to the end thereof a lever. 19, one of whose ends is slotted for the reception of a pin 20 on the block 12 while its other end is similarly slotted for the reception of a pin or projection 2l in the one end of an arm 22. This latter is fixed to a short spindle 23 extending through the plate 24 and having fixed to its outer end a knurled head 25 carrying some tormY of springindicator or pointer 2G. lhe plate 24 1s provided with a semi-cylindrical series of notches indicated at 27 for' theA reden: f tion of the end of this indicati-nghpointer, whereby it and its associated parts are 'firmly held in any given position;

Under conditions ot use it is obvious that 'the turning of the spindle 3 through af fm mmmf; :L cvr filler to the, iec'procable um also cw the sam@ fein 55 11163.11 L) l'H ly cow '105 n hrflww zsmtolfx; 13,10
